Ultracold Cs Feshbach Spectroscopy
Cheng Chin, Vladan Vuletic, Andrew J. Kerman +4
We have observed and located more than 60 magnetic field-induced Feshbach resonances in ultracold collisions of ground-state Cs atoms. These resonances are associated with…
Thermal equilibrium and efficient evaporation of an ultracold atom-molecule mixture
Cheng Chin, Rudolf Grimm
We derive the equilibrium conditions for a thermal atom-molecule mixture near a Feshbach resonance. Under the assumption of low collisional loss, thermodynamical properties are cal…
Pure Gas of Optically Trapped Molecules Created from Fermionic Atoms
S. Jochim, M. Bartenstein, A. Altmeyer +4
We report on the production of a pure sample of up to 3x10^5 optically trapped molecules from a Fermi gas of 6Li atoms. The dimers are formed by three-body recombination near a Fes…
Impact of the Casimir-Polder Potential and Johnson Noise on Bose-Einstein Condensate Stability near Surfaces
Yu-ju Lin, Igor Teper, Cheng Chin +1
We investigate the stability of magnetically trapped atomic Bose-Einstein condensates and thermal clouds near the transition temperature at small distances 0.5 microns < d < 10 mic…
